Sorry dawg M4 runs ring in 7:52, also C7 is lighter than M4 so I don't see how elevation mix will make heavier M4 perform better than Vette??, C7 has nothing to worry about.
Corvettes always looked close to Ferraris, Mustang got look from Aston Martin, what's your point? The reason why mustang was harder design (wasn't) because Ford was afraid to go with bigger leap forward and decided to play safe... What we could get..
Yet a lot of people are negative about new Mustangs design and questions (what makes new Mustang stand out?) just take look at any website with article about new Mustang. http://business.time.com/2013/12/04/this-is-what-fords-all-new-2015-mustang-really-looks-like/
